Clive, Conniving Illusionist

Whenever a player mills one or more creature cards, you may choose one of those cards. If you do create a token copy of that creature but its a 1/1 blue illusion in addition to its other types, it has "If this creature becomes a target of a spell or ability, sacrifice this creature". This ability triggers only once each turn.
{r}: Transform Clive, Conniving Mage. Activate only if if you've attacked with four or more creatures this turn.
